MANUFACTURE OF CHAIR-BACKS, 84C.

SPECIFICATION forming part of Letters Patent No. 327,549, dated October 6, 1885.

Application filed July 6, 1885. Serial No. 170,693. No model.)

To all whom it may concern.-

Be it known that I, HERBERT JOSEPH HAR- WOOD, of Littleton, in the county of Middlesex, of the Commonwealth of Massachusetts, have invented a new and useful Manufacture for use in Making Chair Backs or Seats, 850. and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawing, which is a transverse section of it.

It consists not only of two veneers of wood arranged fiatwise on one another and cemented or glued together, with the grain of one crossing that of the other at or about at right angles,or obliquely thereto, but of two coverings, one thereof being of leather board or paper capable of being pebbled orembossed, and the other being a finishing water-proof covering, the first-named covering being applied and cemented on one of the outer surfaces of the two combined veneers, and being subsequently pebbled or embossed, and colored when necessary, and having applied to it the other or water-proof covering.

In the drawing, A and B denote the two sheets of wood veneering, G the pebbled covering, and D the water-prooffinishing or covering.

I am aware that chair-seats have been made of two sheets of veneer arranged one upon and cemented to the other, with the grain of one crossing that of the other. I am also aware that the flat surface of asingle veneer has been covered with paper. Therefore I do not claim such.

When two sheets of veneer are glued together face to face,with the grain of one crossing that of the other, and to the outer surface of one of them an embossed covering of paper or leather-board is applied and fixed, such covering is protected from being split or cracked in any direction, which it would not he were it fixed to one veneer withouthaving to such veneer another one, as described.

Heretofore in applying cloth or paper to a veneer it has been to prevent the latter from cracking or splitting; but in my present invention such is not the purpose, the object being to support the embossed covering in a manner to enable it to withstand a force tend- I ing to crack or split it and its water-proof finishing-covering in any direction.

My said manufacture when finished has the appearance of very stiff pebbled leathelyand for use as achair seat or back is far preferable 3 t0 and much more durable than embossed or pebbled leather or leather-board.

In making the article constituting my invention one of the two veneers is first to be covered on its two opposite faces with glue.

after which it is to be placed between the other veneer and the covering to be embossed. The whole is next to be introduced between the bed and platen of a powerful press, and to be pressed thereby and held until dry, or nearly so. The connected and pressed veneers and covering are next to he run between the pebbling or embossing rolls of a pebbling or embossing machine, so as to pebble oremboss the covering,as 1norocco-leather is pebbled or em- 7 that of the other, a covering embossed or peb- 8 bled and colored and cemented upon the outer surface of one of such veneers, all being essentially as set forth.

2. A new article of manufacture, consisting of two veneers of wood laid fiatwise one upon 8 the other and glued or cemented together with the grain of one crossing that of the other, a covering embossed or pebbled and glued or cemented on the outer surface of one of such veneers, and a waterproof finishing-covering applied to the pebbled surface, all being essentially as set forth.
